A Custom Aluminum Milled PCB Plate from Billet refers to a precision-machined aluminum plate designed to hold or support printed circuit boards (PCBs), made by CNC milling a solid block (billet) of aluminum. These plates are used in electronics, aerospace, robotics, and other high-performance applications where durability, heat dissipation, and precise mounting are critical.
we put the billet in the 3 axis CNC machine , and mill all the feature.
the plate is very precise in tolerance , most are in +0.05mm or -0.05mm.
the center ribs size in OD75-0.06/-0.01 , it has concentricity requirement 0.1 , roundness 0.05，
as well as flatness=0.15mm , because it is pretty thin for this plate , it is important to keep it still flat , or it will be deviated.
all the radius is 0.25x45degree , no sharp edge , surface is as milled.
not easy to work this plate.
Advantages:
✔ Higher precision than stamped or bent plates
✔ Better durability than 3D-printed or plastic alternatives
✔ Superior heat dissipation compared to non-metal mounts
✔ Fully customizable for complex PCB layouts
Typical Customization Options:
Mounting holes (threaded or through-hole)
Cutouts for connectors, buttons, or displays
Engraved labels or logos
Integrated heatsink fins
Complex 3D geometries
